Abstract

The actuator (10) has a housing (12) with a cylindrical interior sidewall having a grooved inwardly facing circumferential portion. A drive rod (20) extends coaxially in the body and is supported for relative rotation. The drive rod has an end flange positioned toward the body first end for coupling to a second external member and a shaft rigidly attached to the end flange. The flange has a grooved outwardly facing circumferential sidewall portion in the body toward the second end and a smooth body portion between the end flange and the shaft groove (22) sidewall portion.
